The description of Evans place is accurate, it's basic but spacious for the price, with fridge in room and large bed, balcony and small compact dining area.
The location we found to be perfect-short walk to mrt and his local knowledge and tips for using motor cycle taxis and their prices made getting around even easier.
The bed mattress is far too hard. On top of the mattress is one of those rock solid mats that give you pain if you lie in bed.
It's on the 6th floor, no lift, not really a problem unless your tired. with toilet the floor below. This was okay, a little annoying if you sleep naked and need the toilet in the night.
The shower was terrible, barely a dribble, and cold too, almost no point trying to wash your hair and is in the bathroom, over the toilet pretty much which I'm not keen on.
Evan offers a professional laundry service on the 3rd floor I think it was, at 65bht per kilo I think, but he didn't separate the colours so ruined 2 of my tops :( we suggested he didn't charge us for the laundry and he did apologise eventually. Maybe use his washing machines yourself? Or separate your clothing. Was great to have our clothes back clean and dry in just over 12 hours!
Overall I think the place was value for money at £14 in Bangkok (we are only paying top price 400bht/£9 for the rest of our stay in Thailand so we know a good deal) however I did notice the rooms to doors open when the cleaner was there and as long as you don't smoke which we don't, he seemed to have much nicer rooms on the lower floors. Much more pleasing to look at. Maybe they are a different price?
The location is excellent, especially for LGBT, MBT to train station and Lamphini park.
Maybe even more perfect for guys or girls who aren't too fussy about a shower.

I found the dogs difficult, they are very large dogs, they look a bit like wolves. We had been attached by dogs the night before in Bangkok and were nervous on arrival (where we entered alone past the huge dogs) and on exit when one dog got really confrontational- barking, growling and snarling as we tried to pass. We got stuck downstairs and had to wait for a friend of Evans to come and help us. The dogs were impossible to distract and eventually he had to take them upstairs just so we could leave. Left us feeling anxious. Apparently they don't like larger people so if you take off your bags when you arrive and leave and walk in carrying them rather than like some huge shape you will surely be okay.
Thanks for all the info on the area Evan it was very helpful. Would advice staying here if you like / don't mind hard beds and aren't too bothered about your shower.
